The zombies showed up while you were sleeping! The zombie alarm you built goes off as they open the door. You jolt awake to see an alpha-zombie charging through the door. The alphas are zombies that turned all of the zombies in its army. If you can take down this one zombie, all the others pouring into the room should fall as well. Luckily, your group was prepared for this eventuality. Another member of your team has constructed the zombie shocker circuit shown in Figure 5, using some batteries for the voltage source, some rusty metal for the resistors and a coil of wire for the inductor. The switch is just you pulling apart two wires to open the circuit (while holding them by their insulated sheaths).
1. Construct the circuit shown in Figure 15 in the Circuit JS simulator. 2. Start the simulation with switch SW1 in the closed position. You’ve been charging this circuit all night, so you’ll want to let the circuit run for a while (roughly 30 seconds at max…

Due to channel noise, errors are made. As shown in Figure 4.4, the channel is assumed to be symmetric, which means the probability of receiving 1 when 0 is transmitted is the same as the probability of receiving 0 when 1 is transmit- ted. The conditional probabilities of error are assumed to be each e. Determine the average prob- ability of error, also known as the bit error rate, as well as the a posteriori probabilities.arrow_forwardWhat is the bandwidth requirement in Hz for baseband binary transmission at 64 kbps, if the roll-off factor is 0.25?arrow_forward
